Re: unexpected duplicate timestamps

Thanks Michael.
Converting the timestamps to decimal, below, I see how small the interval i=
s.
Lesson learned, system clock cycles are not the cogs of cpu cycles.
I had made the assumption tai64n would always be incremented,
as if the cpu clock was driven by the system clock.
